Title:
Integrated Computational Materials Engineering (ICME) for Lightweight Materials
Abstract:
Pacific Northwest National Laboratory (PNNL) is the only Department of Energy (DOE) national laboratory recognized by industry with signature capabilities in Integrated Computational Materials Engineering (ICME), and our research objective is to develop microstructure-based predictive modeling tools in understanding the influences of meso-scale defects and heterogeneities as well as their evolution kinetics on the overall mechanical properties, including ductility and failure, of engineering materials. We are the key bridge between the lower length scale material science and discovery to the larger length scale materials engineering and application. We are currently developing ICME-based predictive capabilities in lightweight metallic materials, including nuclear fuel and structural materials, multiphase advanced high strength steels, Mg castings, aluminum sheets, as well as amorphous glass systems for transparent armor applications. In addition to bulk material property predictions, Dr. Sun’s team has developed an integrated suite of modeling tools considering various manufacturing processes such as cutting (shearing), stretching, forming, welding and joining, in final property predictions. In this presentation, Dr. Sun will present PNNL’s ICME modeling framework and its applications in various lightweight materials including 3rd generation advanced high strength steels, aluminum sheets and Mg casting.
